How To Trick Your Brain To Hold On To Positive Habit Changes


BOOK REVIEW

Making Habits, Breaking Habits, Author: Jeremy Dean.

By Jane Porter – The notion that a habit takes 21 days to form if you stick to it every day is a myth.

On average, a habit takes more like 66 days to form, with more intensive habits like doing 50 sit-ups every morning taking around 84 days to form. But these figures will often vary greatly from person to person.

Forming habits that stick isn’t about finding a magic number. It’s about being aware of your behaviors and environment and their effects on your brain. more> http://tinyurl.com/orahkqu

The Global Problem With Overdiagnosis and Overtreatment


By Alexandra Sifferlin – Current screening guidelines lead to an overdiagnosis of diseases like cancer, which results in overtreatment for ailments that might never seriously impact a person’s health.

Instead of recommending lifestyle modifications proven to work, like cutting back on alcohol and exercising more, many doctors opt for drugs because they want to do something right away without having to rely on the often-unhealthy environment beyond their office walls. more> http://tinyurl.com/ptb85gs

A Secret to Laser Brain Surgery? Slice the MRI Machine in Half

GE –  In the early 1990s, Harvard radiologist Dr. Ferenc Jolesz devised a clever way for killing brain tumors with a laser. But he ran into a hard obstacle: the skull.

Jolesz wanted to send a laser beam along a fiber optic strand inserted through a hole in the patient’s cranium. The beam’s intense heat would destroy the target. But he couldn’t see where the beam was going. “It was like trying to evaporate an apple seed inside a whole apple without cutting it.”

Jolesz thought magnetic resonance imaging could help. The right MRI machine would allow doctors to see inside the body, monitor temperature changes inside the skull, and perform surgery at the same time.

One problem: a machine like this did not exist. Then as now, most MRI machines enclosed the patient in a tunnel at the center of the magnet. This design made brain surgery impossible.

But a GE executive who knew about Jolesz’s project introduced him to Trifon Laskaris, a medical imaging pioneer working at GE’s research labs in upstate New York. Laskaris listened to Jolesz and came back with a design that sliced the multi-ton MRI magnet in half. The redesigned machine looked like a double donut with enough space between the two rings to give the surgeon access to the patient. “We could image the patient and operate at the same time,” Jolesz says. “Not only laser procedures could be done, but all types of open surgeries.” more> http://tinyurl.com/l2expyb

What Happened When I Woke Up Two Hours Earlier For A Week


By Rachel Gillett – The idea is that having a time in the day where there is no pressure and no expectations from other people would result in better focus and more creative thinking.

The first day I had so many endorphins shooting around my body that I almost felt manic–but in a good way.

My mind was bursting with thoughts and ideas, possibly because of the effect exercise has on our bodies, but also because I felt unencumbered by the need to start working immediately. My inner dialogue just wouldn’t shut up on the walk to work. more> http://tinyurl.com/m2br9hz

The Ways Food Tricks Our Brains


By Derek Thompson – Simply labeling a food as “healthy” makes it taste worse. But what tricky qualities make unhealthy food taste healthy?

Researchers asked participants to eat bite-sized brownies while watching TV (fun!). Some of the brownies were hard and some were soft. Subjects ate more soft brownies when they weren’t prompted by any questions. But when they were told to think about calorie content, they switched and suddenly ate more rough brownies.

To the eating brain, harder-to-eat equals healthier-to-eat. more> http://tinyurl.com/nmnqfl8
